II Peter 1:7

"And in your godliness brotherly kindness"; not suffering your godliness to be moroseness, nor a sullen solitary habit of life, but kind, generous, and courteous [ALFORD]. Your natural affection and brotherly kindness are to be sanctified by godliness. "And in your brotherly kindness love," namely, to all men, even to enemies, in thought, word, and deed. From brotherly kindness we are to go forward to love. Compare Th1 3:12, "Love one toward another (brotherly kindness), and toward all men (charity)." So charity completes the choir of graces in Col 3:14. In a retrograde order, he who has love will exercise brotherly kindness; he who has brotherly kindness will feel godliness needful; the godly will mix nothing stoical with his patience; to the patient, temperance is easy; the temperate weighs things well, and so has knowledge; knowledge guards against sudden impulse carrying away its virtue [BENGEL].

In this chapter we have, I. An introduction, or preface, making way for, and leading to, what is principally designed by the apostle (Pe2 1:1-4). II. An exhortation to advance and improve in all Christian graces (Pe2 1:5-7). III. To enforce this exhortation, and engage them seriously and heartily to comply with it, he adds, 1. A representation of the very great advantage which will thereby accrue to them (Pe2 1:8-11). 2. A promise of the best assistance the apostle was able to give to facilitate and forward this good work (Pe2 1:12-15). 3. A declaration of the certain truth and divine origin of the gospel of Christ, in the grace whereof they were exhorted to increase and persevere.
